In this post, we'll learn exactly how styled-components works by building our own mini-version.

Image To Text Conversion With React And Tesseract.js

Data Science Cheatsheet 2.0

A helpful 5-page machine learning cheatsheet to assist with exam reviews, interview prep, and anything in-between. This resource is not meant to be a comprehensive deep dive into any specific model, but rather a quick refresher on a few of the most fundamental machine learning algorithms. The reader should have at least a basic understanding of statistics and linear algebra, though beginners may find this cheatsheet helpful as well.

Inspired by Maverick's Data Science Cheatsheet (hence the 2.0 in the name), located here.

Topics covered:

Linear and Logistic Regression
Decision Trees and Random Forest
SVM
K-Nearest Neighbors
Clustering
Boosting
Dimension Reduction (PCA, LDA, Factor Analysis)
Natural Language Processing
Neural Networks
Recommender Systems
Reinforcement Learning
Anomaly Detection
Time Series
A/B Testing

This cheatsheet will be occasionally updated with new/improved info, so consider a follow/star to stay up to date.

Future additions (ideas welcome):

iPod.js

An iPod Classic that connects to Apple Music and Spotify. Built with React & Styled Components

An iPod Classic that connects to Apple Music and Spotify. Built with React & Styled Components

by Tanner Villarete | LinkedIn | Website

Before the days of streaming services, we relied on physical devices to store our limited libraries of music. Now with the streaming age, we no longer rely on physical storage and have endless hours of songs at our disposal. This project is an homage to the good 'ol days. A mix of the old and new. Experience the iPod Classic you used to own that now connects to Spotify and Apple Music — the two most popular music streaming platforms in the world.

I built this thing to be very extensible – to the point where it can even run games (like brick!). In the future I might consider adding a few more little apps and easter eggs (theming?).

Details

Here's a breakdown of the Full Stack:

Frontend:

JS: TypeScript, React (Hooks, Context)
CSS: Styled Components, Framer Motion (for some of the animations)
